IMPROVEMENT lN MACHINERY FORLFEEDING CARDINGeENGI'NES.

Specification forming part of Letters Patent No. 37,304, dated January6, 1863.

To all whom it may concern:

-Be it known that I, STEPHEN R. PARK HURST, of the city and State-of NewYork,

have invented, made, and applied to use a certain new and usefulImprovement i nFeed-g chine, and,Fig. 2-is a plan of one side of thesaid feeding-table. 1 V

- Similar marks ofreference denote the same teeth'of. the table carry upsaid fibers, and the parts. i I

In carding and other machinery for workin g cotton, wool, and otherfibrous material it is usual to supply a certain amount of the stapleupon a given size of belt or apron formingthe feeding device in orderthat the fibrous bat or sliver may be uniform as delivered from themachine but these feeding belts or aprons are very liable to slip orbecome obstructed,

and the supply of fiberto the machine being lessened'or stopped causesthe bat or sliver to break or be thinner at the particular part, whichderanges the subsequent operations of spinning, 850.

The nature of my said invention consists in a rotary feeding tableformed of a cylinder covered with teeth, and on which the-material isdistributed from a hopper and evened by hand. I also employ a series oftoothed rollers in combination with this feeding-table to open the locksof wool previous to their being taken by the cleaning or cardingmachinery. By this device I am enabled to supply the fibrous materialwith greater uniformity than by the aprons heretofore employed, andthere i is less risk of the supply of fiber to the machine beingarrested or checked, and the fibers are opened, loosened, and separatedby a slow movement, that prevents the injury to the cotton or wool bythe-pickers, breakers, or cleaners heretofore employed. Y

In the drawings, gis my rotary feeding-table mounted on the shaft 1, andsaid table'is revolved by means of gearing or any suitable mechanism.

h is an inclined board forming a hopper.

against the side of this cylindrical feeding-ta ble,-and curved sidepieces, is, prevent the fibers falling ofl' at-the ends of thecylindrical feed- .--ing-table.i The periphery of this cylindricalrotary feeding-table is divided by means of blocks, pins, or similardevices (shown at t t t) whereby the operator on attendant is enabled ihas passed the hopper-board h the given amount of fibrous material isplaced on said board and distributed along the same. The

attendant sees that the mass is evenly distributed between thisindicating-block i and the next one,which is easily done, as the fibersrestupon said cylindrical feeding-table, and

then the operation is repeated by adding the given amount of fibrousmaterial again into the hopper.

Z is a roller that presses the fibers to the teeth on the. cylindricaltable, and this roller may receive an end movement, asiit revolves bymeans of a cam, and stationary stud or other suitable device by whichthe looks or bunches of fibrous material may be spread transversely ofthe table, causing the mass to be presented to the cleaning 'or cardingmachinery in a uniform bat. The fibers might be taken off the feed-tableg by a pair of feed-rollers to the'or-- device would not fully carry outmy invention,

by means of which the feed-rollers are dispensed with andtheircompressing action on the fibers avoided. I provide, therefore, thetoothed rollers or cylinders n and 0, which take the fibers from theteeth of therotaryfeeding-table, the cylinder 0 entirely cleaning theteeth of said table and being itselfcleaned by the cylinder at. Thisoperation opens, combs, and partially cards the fibers Without liabilityto cut or break them, as the motion is slow.

a is the ordinary licker-in to the cardingcylinder 0 on the shaft b, andd e represent the usual workers, and f the doft'er. The opening,combing, and loosening operation on the wool or other fiber is stillmore promoted by the cylinder m, that acts between the cylinder a and nto separate any-locks or bunches of fiber and open them; and saidcylinder m also removes surplus fibers from the roller 1. these meansthe fiber is in a proper condition by the time it reaches the portion ofthe machine adapted to cleaning or carding, so. that f The teeth on therespective'rollers and cyl inders may be'made of wire, or in any usual 1p, traveling on rollers q q, and carrying crossrods or scrapers, thatdraw the fibers along over a screen or netting r to the said cylindricalfeeding-table g. The dirt falls away through the netting r, and thefiber is taken by the teeth of the feeding-cylinder g and ear ried upagainst the curved guards and mentered into the carding-machine, thuseflecting a saving of the said fiber and rendering unnecessary theoperations now resorted to for saving this-fiber and returnin it tothecarding-machine'.

-I 'do not claim a series of toothed cylinders. or rollers acting withthe cardin g-cylinder,

as in the patentof Jeptha Dyson, December 6,1859; but

What I claim, and desire to secure by'Letters Patent, is v 1.. Thecylindrical rotary feeding-table g, to supply the fibrous material tothe cleaning or carding machine, substantially as specified.

' 2. The roller Z, in combination withthe said cylindrical rotaryfeeding-table g, for the purposes and as specified. Y

3. The belts p p, screen r, and curved guard s, in combination with thesaid cylindrical rotary feeding-table g, for the purposes and asspecified.

4. A series of toothed cylinders, in combination with the toothedfeeding -table, for opening, combing, specified.

In witness whercofl have hereunto set my signature this 10lh day ofSeptember, 1862.
